Is this file available for use with a nanocom? Should have a new toy next week and I'd like to sort this prior to the drive across to Ireland?

Bumping this up as mine just came back from the stealer with similar symptoms (thumping at gentle acceleration and occasionally on slowing). Their verdict was that the rear diff needs replacing (apparently that was the case with an RRS with same symptoms they had in a few months ago).
Now I'll be driving back home in the next three months or so (yep, all the way up to Cheshire!), in large part to sort this out as I do not trust the franchise here... From this thread however, it sounds that a software upgrade may resolve the issue?
I know of no one with a multi-VIN MSV2 down here, so the question is whether the LR software platform will be able to do this resetting?
Another question: does the calibration require mechanical work? (my diff oil check came out clean)
...and finally, if I do need a new rear (locking) diff, how much are these roughly?

(still less for me than a one-way trip just for this though... )

Mine has restarted clunking when accelerating from a slow crawl/coast immediately after braking...
I do hope it isn't the diff!
What I have noticed is, when lifting my foot off the brake pedal, it's pretty slow at returning back to it's rest position, enough for the brake lights stay on for approx half a second or so after taking my foot of the pedal...
I was wondering if this was confusing the 'box and/or torque converter into thinking I'm pressing both pedals at once...
I'm getting to the point where I just want this sorting now, it's doing my head in!flickr

So I had the oil changed in both front and rear diffs and the adaptive transmission reset (they also reset the diff ECU???)
Noticeable difference so far in slow starts but still noticeable thunk at gear changes...
Oils didn't look or smell too bad, neither did the plugs:

Confused as to the part numbers however: invoice and box show LR019727, bottle reads Castrol Differential BOT720: is this the correct oil for the locking rear diff?

Front oil was quoted as TYK50010, bottle reads Castrol SAF-XO 74W-90 (both in LR packaging) - is this the correct front oil?

Not holding much hope on this as the gear changes thump is still there (gearbox was flushed and reset a few months ago). Am I looking at a gearbox issue, a diff issue or a transfer box issue?

When was the last time you used low range?
might sound daft, but after using low range, mine seems to sort itself out for a bit... no idea why, might be just coincidental, but worth dropping it in low range and driving through the gears a couple of times...flickr

rear diff
Just had my dear diff replaced, ever increasing thunk at low speed changes has gone and despite trying I can't get it to do it again. Metal in oil and gearteeth knackered - reported as excessive backlash.
Still considering the software fix as a preventative measure to protect the drivetrain.

Geoff - can you pls have a look at the below - and let me know if trying to update the auto transmission soft is advisable (not sure if the soft you are updating is newer or not). I am having this "thunk" as well.
HARDWARE NUMBER THC500061
SOFTWARE NUMBER NNV503891
ASSEMBLY PART NUMBER NNW507910
MAIN CALIBRATION PART NUMBER NNS504620
Also - is there aby specific guideline for the trasnfer clustch calibration - or just push the button on MSV2 ?

Guys-anyone can have a quick look and confirm if the above needs be updated?
For the transfer clutch calibration-any special process to be followed?
